Emergency? Yes! No! (Urgent Care or ER?)

It is always fascinating to watch medical television shows that center around the emergency room and the doctors making life and death decisions that culminate in thirty to sixty minutes. What is not often seen are the difficult choices that have to be made when a relative or friend is injured, falls or has trouble breathing; is it life-threatening, what steps should be taken, does this mean a trip to the ER or is it something that can be taken care of at an urgent care center?
